Abstract
A simple laser rack clamping device with the adjustable inclination angle comprises a base. The base is fixedly connected to a laser rack moving tabletop through bolts. An upper cover board and a lower cover board are installed at the upper end and the lower end of the base. The middle of a spindle penetrates through an inner hole of a boss in the middle of the base. The lower end of the spindle is connected to the lower cover board and the upper end of the spindle is connected with the upper cover board through a side clamp on the spindle. The side clamp is provided with a compass. The upper cover is marked with scale marks of the rotating angle. The upper portion of the spindle is connected with an upper clamp and the lower portion of the spindle is connected with a lower clamp. A workpiece is fixed between the upper clamp and the lower clamp. The spindle rotates to drive the workpiece to rotate, so that the inclination angle of the workpiece fixed between the upper clamp and the lower clamp is generated. The rotating angle of the spindle is changed and determined by adjusting the included angle between a pointer and the scale marks of the upper cover board. According to the device, the inclination angle between the axis of a hole of the workpiece and a laser beam can be continuously adjusted within the range from -90 degrees to +90 degrees, operation is simple, and the experiment research requirements for machining perpendicular holes and inclined holes through lasers are met.

In aircraft industry and precision instrument, the extensive use of micro hole, makes micro hole machining technology receive the extensive concern of domestic and international scientific circles and engineering circles.Along with before aero-turbine, temperature improves constantly, the hot-end component of engine all have employed air film cooling technology, Film Cooling is determined by factors such as the Flow Field Distribution in the geometry of film cooling holes, Flow Field Distribution and cold air path and in hole, and therefore the quality of film cooling holes is directly connected to the quality of Film Cooling.The tilt angle varied scope on film cooling holes central axis and surface, between 30 ° ~ 90 °, so in Laser Processing aperture experimental study, not only needs to pay close attention to upright opening processing, also needs to pay attention to the processing of oblique straight hole.The motion platform of the laser configurations that experimental study is used is only applicable to process upright opening, can not realize inclined hole processing.
Some research units and individual adopt the angular displacement platform of photoelectric instrument manufacturers produce to make workpiece fixed thereon realize different angles at present.And photoelectric instrument manufacturers design and mainly consider the accuracy of displacement platform, stability, sensitivity, moulding and Cost Problems when producing electric angle displacement platform or manual angle moving stage.Workpiece how is made to realize the problem of different angles tilt variation for angular displacement platform, Ge great photoelectric instrument manufacturer employing arc-shaped guide rail ensures precision when moving, and the inclination angle stroke range adopting arc-shaped guide rail to realize is very little, general between ± 3 ° ~ ± 30 °, Laser Processing wide-angle tilt hole machined technical study can not be met.Most angular displacement platform adopts Worm Wheel System, although precision and stability is high, its compact conformation, difficulty of processing are large, require that each part has higher machining accuracy, technological requirement is high, and therefore this angular displacement platform cost is higher, is unfavorable for saving reasearch funds.Recently also there is people's designed, designed with the clamping device of angle of inclination regulating action, realize the adjustment of special angle, but can not be adjustable arbitrarily within the scope of certain angle, and complex structure, limitation is excessive, is unfavorable for experimental study.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of simple laser stand clamping device of tilt adjustable, can make workpiece hole axis and laser beam be that inclination angle regulates continuously within the scope of-90 ° ~+90 °, and operate extremely simple, meet the experimental study requirement of Laser Processing upright opening and inclined hole, improve laser instrument auxiliary facility.
In order to achieve the above object, the present invention adopts following technical solution:
A simple laser stand clamping device for tilt adjustable, comprises pedestal 1, and pedestal 1 four jiaos all has through hole, is bolted and makes it be fixed on laser stand sports platform face; Upper cover plate 2 is connected to the upper end of pedestal 1, lower cover 11 is arranged on pedestal 1 lower end, through the endoporus of boss in the middle part of pedestal 1 in the middle part of main shaft 5, main shaft 5 lower end is connected on lower cover 11, and upper end is bolted with upper cover plate 2 by the side fixture 4 of welding on main shaft 5, and side fixture 4 is provided with pointer 3, upper cover plate 2 is carved with the scale of the anglec of rotation, main shaft 5 top is connected with fixture 7, and main shaft 5 bottom is connected with lower clamp 9, and workpiece 8 is fixed between fixture 7, lower clamp 9.
Described main shaft 3 both ends are provided with groove, are upper groove 6 and low groove 10 respectively, and hex bolts screws in upper fixture 7 and lower clamp 9, by pressing upper groove 6 and low groove 10 fixing upper fixture 7 and lower clamp 9 respectively.
Compared with existing clamping device, tool of the present invention has the following advantages:
1, can not only horizontal holding workpiece, the axis of workpiece 8 can also be made to have certain angle relative to laser beam, and angle can within the scope of-90 ° ~+90 ° consecutive variations, overcome clamping device in the past and can not change angle of inclination, only to tilt several special angle and the little defect of angular displacement platform adjusting angle scope.
The side fixture 4 that main shaft welds and upper cover plate 2 are fixed together by the mode of 2, being pressed by screw, prevent workpiece 8 inclination angle processed from changing, improve the stability adding operating mode in man-hour, this mechanical lock method is simple and practical, has good operability.
3, the upper groove 6 at main shaft both ends and low groove 10 make fixing on main shaft 5 of fixture 7 and lower clamp 8, reduce the requirement to elongated hole in pedestal 1 and main shaft 5 machining accuracy.
4, each component structural forming this laser stand clamping device is all simple, and without special manufacture requirements, difficulty of processing is low, and the component number related to is less, all adopt aluminum alloy materials manufacture, required cost is low, total is simple and practical, has obvious superiority in economy.

Fig. 1 is clamping device overall schematic.
Fig. 2 is that angle of inclination is selected and schematic diagram fixed by main shaft.
Fig. 3 is that fixture locates schematic diagram on main shaft.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described.
See Fig. 1, a kind of simple laser stand clamping device of tilt adjustable, comprises pedestal 1, and pedestal 1 four jiaos all has through hole, is bolted and makes it be fixed on laser stand sports platform face, upper cover plate 2 is connected to the upper end of pedestal 1, lower cover 11 is arranged on pedestal 1 lower end, through the endoporus of boss in the middle part of pedestal 1 in the middle part of main shaft 5, the radial motion of endoporus constraint main shaft 5, main shaft 5 lower end is connected on lower cover 11, main shaft 5 is rotated more stable, upper end is bolted with upper cover plate 2 by the side fixture 4 of welding on main shaft 5, in order to retrain the axially-movable of main shaft 5, as shown in Figure 2, side fixture 4 is provided with pointer 3, upper cover plate 2 is provided with the scale of the anglec of rotation, change by the angle between adjustment pointer 3 and upper cover plate 2 scale and determine the anglec of rotation of main shaft 5, the mode of this fixed main shaft 5 can make main shaft 5 anglec of rotation regulate continuously, thus drive workpiece 8 angle of inclination continuously adjustabe, main shaft 5 top is connected with fixture 7, main shaft 5 bottom is connected with lower clamp 9, workpiece 8 is fixed on fixture 7, between lower clamp 9.
